The 81-set [[omega].sub.4] has the
sextic equation [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII].
The rovibrational constants determined for the excited state consisted of the three rotational constants, the band center, all five quartic, and two
sextic centrifugal distortion parameters.
The trends found to be significant are the lineal, F( 1, 28) l4.37, p <.001; quadratic, F(1, 28) = 5.l3, p < .05; quintic, F(1, 28) = 4.83, p < .05; and
sextic F(l, 28) = 7.27, p < .01.

Suppose that C is an R-join-type
sextic with component type T.
The

N = 5, giving a geometrical construction of the congruence of lines [B.sub.MA] in [P.sup.5] in this way obtained: it results to be a first order congruence and a smooth Fano 4-fold in [P.sup.11] in the Plucker embedding; its focal locus is a
sextic threefold X such that the lines of [B.sub.MA] through a general point of X form a (planar) pencil.
Some well-known DWPs in the literature are the quartic potential [6], the
sextic potential [7], the Manning potential [2], and the Razavy potential [8].
Such a curve was first studied by Zariski in [15] where a
sextic of torus type (2, 3) appears as the dual of a smooth cubic curve.
On the other hand, during the last decades, a great deal of attention has been given to the study of the Schroodinger equation with QES double-well potential (DWP) including the quartic potential [22], the
sextic potential [23], and the Razavy potential [24].
